Patented Aug. 23, 1932 UNITED STATES PATENT OFFICE MORGAN J'. HAMMERS, OF STANFORD, CONNECTICUT, ASSIGNOR T0 PETROLEUM HEAT AND POWER COMPANY, OF NEW YORK, N. Y., A CORPORATION OF DELAWARE on. BURNING APPARATUS Application led November This invention relates to an improvement in oil burning apparatus, and has for one of its objects the provision of a construction which is exceedingly eiicient in operation, the boiler or heat absorbing medium employed being of such new and novel construction and so disposed with relation to the burner as to insure maximum efficiency in operation.

A further object of the invention is the rovision of a construction in 'which the urner and boiler may be said to constitute a unitary structure, thereby enabling a manu-- facturer to supply a complete heating equipment ,with the assurance that the same w1ll function properly.

A still further object of the invention is to provide a completely enclosed structure, the heat absorbing'medium and the burner being enclosed in an insulated casing, the casing and the heat absorbing' medium being so constructed and so dis osed with reference-to the burner that the hot gases resulting from the combustion of fuel in the tire chamber will be confined and directed against the heat absorbing medium.

A still further object of the present invention is the provision of a construction in which the heat absorbing medium and the burner are so disposed relatively that While constituting or providing a unitary structure the burner is readily removable :tor inspec- I the apparatus as shown in Fig. 2;

tion and repair. Y

A. still further object of the invention is the provision of a construction employing a plurality of Water circulating supporting tubes intermediate the Water jacket of the combustion chamber and a steam or hot water chamber above the combustion chamber, in

conjunction with a water circulating sheet in the Water jacket, thereby promoting very rapidly an unobstructed Water circulation.

A still `further object of the invention is the provision of a onstruction embodying coiled eat absorbing members intermediate the water jacket and the chamber at the top of the structure, these members being of copper or other material providing :tor very rapid heat transfer, and so disposed With reference to the burner that hot water or steaml is gen- '4, 1830.

erated almost instantaneously. The present 'lhe present lnvention also provides a con.-

struction in which due to the rapid circulation of the Water and the practically instantaneous generation of. steam or hot water, the formation of scale in the principal heat absorbing portions of the boiler is prevented to a very large extent.

As already pointed out, the present invention provides an enclosed structure, and in this connection it is to be noted that the casing constituting the enclosureJis very easily removable in the eventl it is desired to cleany the inside of the boiler. I

ln the drawings accompanying this application:

Figs. 1 and'Q are side and front elevational views of an embodiment of the present invention;

Fig. 3 is a vertical section through the apparatus shown in Fig. 1;

Fig. 4 is a similar section taken through Fig. 5 is a section on the line 5--5 of Fig. 3;

lig. is a section on the line 6-6 of Fig. 3; an

Fig. 7 a section on the line 7-7 of Fig. 3.

Referring to the drawings in detail: The heat absorbing medium has been illustrated in the form of a boiler of novel construction and comprising a steam or hot water chamber designated l at the upper part thereof., a water circulating chamber or Water jacket 2 at the bottom of the structure, and intermediate heat exchange coils 3. As will be seen from Figs. 5 and 7, for instance, the chambers 1 and Q are roughly circular in plan, While the heat exchange coils 3 are arranged in a circle in spaced relation. rFliese coils are of Copper or some other suitable material in which heat transfer is practically instantaneous.

The coils are connected top and bottom to the steam or hot water chamber chest 1 and water jacket 2 by unions 4 and 5. By simply disconnecting the proper unions it will at once be apparent that any coil may be removed for repair or replacement independently of the other coils.

In addition to the -foregoing the present apparatus provides a plurality of water circulating and supporting tubes designated 6 and likewise arranged roughly in a circle. Four fof these `tubes have been shown by way of illustration, and it is to be noted that they are so placed with reference to the coils 3 as not to interfere with the independent removability of these coils already referred to.`

The steam or hot water chest or chamber is provided with lues 7 The water jacket 2 as will be seen from Fig. 4, for example, surrounds the combustion chamber designated 8 and into which projects the burner 9 as will be pointed out hereinafter. Within this jacketand spaced from the Walls thereof is a water circulating sheet 10, provided with large notches or cutouts 11L and 12 in its upper and lower edges, respectively. This water circulating sheet it will be appreciated promotes circulation of the water in the acket, and takenA in conj unction with the tubes 6 and coils 3 insures rapid circulation'of all the Water in the system. As a result the formation of scale in the principal heat absorbing portions of the boiler is Y reduced to a minimum.

- Beneath the water jacket 2 is-a plate 13 on which rests the structure of the water jacket, this plate being cutout at the center as shown to permit ofthe insertion of the burner 9 therethrough into the combustion chamber. It maybe noted at this point that the Wall of the combustion chamber aboutY the burner is lined with fire brick or some other such suitable material, shown at 14.

Bolted to the underside of the supporting plate 13 is a burner supporting plate 15, the urner being suspended from this late. The burner is of the vertical type an comprises a vertically mounted driving motor 16, on the armature shaft 17 of which is mounted a rotary atomizing cup 18, the cup as will be appreciated rotating about a vertical axis.

- Surrounding the cup 18 is an air deflecting rino' 19, while 20 indicates a fan housin witliin which is mounted a fan (not shown and which supplies air to the interior of the cup 18 as Well as to the area immediately surrounding the exterior of the cup. Oil is supplied to the cup through pipe or conduit 21. This burner structure is all described and claimed in detail in a co-pending application Serial No. 493,263 filed November 4, 1930 so willl not be' referred to herein in further de tai exchange coils to said heat absorbing um, water circulating tubes intermediate the From the description thus far given it will be seen that the present, construction is such as to insure the maximum in eficiency of operation, the chamber 1 and jacket 2 as well as the coils 3 and tubes 6 being so arranged 'wv The casing which is designated 22 is heat in. so

sulated and on the outside is covered with metal. The sides and the top of the casing are independently removable. The door 23 is removable with the front plate of the casing. This is of great convenience in that it 8 permits of access to the interior of the apparatus without disassembling the Whole unit. For example, the front plate of the casing may be removed independently of the sides and this permits of access to the whole front of the interior mechanism. The lower part fof the casing of the apparatus is not necessarily heatl absorbing and comprises front plate and side members designated 25.

These canbe removed independently so that access may be had to the burner.

remove the burner for purposes of repair or lnspection, 1n which case 1t 1s only necessary be had to the bolts by which the burner is held in place together with the various other connections such as the oil connection, for

example, so that the burner may be taken out 105 bodily.

The automatic controls for the e uipment may all be placed on the outside of t e casinrof the apparatus so las to be accessible at a times.

For convenience in handling the casing is provided with a plurality of holes 26 nor'. mally plugged with plugs 27. These plugs can be removed and eye bolts substituted through which bars may be slipped to permit n of the whole apparatus being What is claimed is 1. In apparatus of the class described, the combination of an open to water jacketed combustion chamber, a uid chamber disposed above the combustion chamber, heat exchange coils intermediate the water jacket of the combustion chamber and the fluid chamber, said coils being so disposed relallfted or raised.
